Actually, the Yamaha S1100 or S2100 integrated amps would be a lot brighter and more forward than the Denon/Vincent sound. The same would be said about the Bryston integrated.
Class D amps will not be as bright or solid-state sounding as the Yamaha or Bryston. They are going to be a very high resolution and very smooth amp. Very neutral (not warm / not bright). However, many Class D amps just do not have the high frequency extention and "air" that Class AB amps have. Many love the Class D offerings, but my hearing and personal preference is sensitive to that lack of "air" that Class AB has.
